A model for simulating river and reservoir temperatures with applications for anadromous fish management

Creator:

Currie, James William

Abstract:

A problem confronting the Corps of Engineers and other water resources planners in the Pacific Northwest is the prediction of anadromous fish enhancement benefits that would result from a proposed high dam project. These benefits are expected from augmenting natural streamflows with relatively cold reservoir withdrawals. The resulting increased streamflows...

AN ABSTRACT OF THE THESIS OF JAMES WILLIAM CURRIE for the
Fate of ammonia volatilized from a confinement livestock facility

Creator:

Hoffman, Eldon Randall

Abstract:

A conceptual model was developed to further the understanding of the evolution and fate of volatilized ammonia in the atmosphere. Recent trends in livestock rearing have been toward confinement facilities in which high animal concentrations are maintained. One of the impacts of these facilities has been increased local concentrations of...

Determination of equilibrium partial pressure of ammonia gas above anaerobically digested sewage sludge

Creator:

English, Charles Joseph

Abstract:

A laboratory study of anaerobically digested sewage sludge was performed to measure equilibrium constants for ammonia in the sludge. Measured constants describing the solution and dissociation of ammonia in sludge were compared to theoretical constants obtained from thermodynamic data. No significant difference was found between these two sets of constants....
